Waning Gibbous on . The illuminated surface of the moon is 78% and getting smaller. The lunar cycle is 19 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is leaving the last ∠4° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.
Previous main lunar phase is the Full Moon before 5 days on 18 September 2100 at 11:32.
Next Full Moon is the Hunter Moon of October 2100 after 24 days on 18 October 2100 at 04:06.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 7.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1913".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1245 of Meeus index or 2198 from Brown series.
The length of this lunation is 29 days, 9 hours and 13 minutes and it is 1 minute longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 3 hours and 31 minutes shorter than the mean synodic month length. It is 2 hours and 38 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠320.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠340.4°.
1 day since point of apogee on 22 September 2100 at 16:20 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 4 October 2100 at 21:58 in ♎ Libra.
The Moon is 404 839 km (251 555 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 359 240 km (223 221 mi).
6 days after ascending node on 17 September 2100 at 01:56 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 1 October 2100 at 12:43 in ♍ Virgo.
11 days since the last southern standstill on 11 September 2100 at 14:42 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.345° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠28.300° at the point of next northern standstill on 26 September 2100 at 01:39 in ♊ Gemini.
6 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 10 days on 3 October 2100 at 18:03 in ♎ Libra the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
